Facebook acts after hack attack

Facebook is tightening up security on its site by offering users an encryption service following a number of high-profile hacks, including that of founder Mark Zuckerberg.
The company is urging users turn on the service – called HTTP – if they frequently use Facebook from public Internet access points found at coffee shops, airports, libraries or schools.
“We currently use HTTPS whenever your password is sent to us, but today we’re expanding its usage in order to help keep your data even more secure,” the company said in a blog post.
Facebook is also introducing what it calls “social authentication”. If Facebook suspects your account has been compromised, it may show you pictures of your online friends and ask you to identify them.
“We will show you a few pictures of your friends and ask you to name the person in those photos. Hackers halfway across the world might know your password, but they don’t know who your friends are,” the company added.
For many companies, these facilities come as standard. For instance, Google automatically turns on encryption for all Gmail users, while Microsoft also offers encryption as an option with Hotmail.
